Free Wisconsin Gun / Firearm Bill of Sale
Wisconsin is a permissive-firearms state: no permit-to-purchase, no waiting period, no state registry, no assault-weapons ban, and no magazine-capacity limit. Private-party transfers between Wisconsin residents who are not prohibited persons require no background check under state law (federal law still bars knowingly transferring to a prohibited person). FFL handgun transfers run a Wisconsin DOJ Firearms Database check; long-gun transfers run NICS only. Concealed carry still requires a Wisconsin CCW permit — Wisconsin has not adopted constitutional carry.

Wisconsin Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
Private-party firearm sales in Wisconsin between non-dealers are generally not subject to state sales tax. Sales through a licensed FFL dealer are subject to 5% state sales tax plus 0.5% county tax. Wisconsin does not impose a separate firearms or ammunition excise tax beyond the federal 10–11% Pittman-Robertson excise tax (paid by manufacturers).
Inspection Requirements
Wisconsin private-party firearm transfers do not require a state background check. FFL dealer transfers run a state DOJ Firearms Database check (Wisconsin's state-level system) plus the federal NICS check, with a 48-hour delay possible for handguns if the state check is not immediate. Wisconsin eliminated the 48-hour handgun waiting period in 2015. Long-gun (rifle, shotgun) transfers at FFLs require only NICS, not the state DOJ check.
Wisconsin Gun / Firearm Sale — Step-by-Step Checklist
- Verify the buyer is a Wisconsin resident, age 18+ (long gun) or 21+ (handgun), and not a prohibited person under federal/state law
- Bill of sale: make, model, caliber, serial number, buyer name and address, seller name and address, and date
- Both parties keep signed copies for their records (no state filing required)
- Optional but recommended: ask for the buyer's Wisconsin driver's license or CCW permit and note the number
- For interstate sales: federal law requires the transfer go through an FFL in the buyer's home state
- For NFA items (suppressors, SBRs, machine guns): use ATF Form 4 with $200 stamp; Wisconsin allows NFA
- Store the bill of sale safely — your only proof if the firearm is later recovered or used in a crime
Common Pitfalls
- Knowingly transferring to a prohibited person (felon, domestic abuser, drug user, etc.) — this is a federal felony regardless of Wisconsin's permissive laws
- Selling a handgun to an out-of-state buyer face-to-face — federal law requires an FFL transfer in the buyer's home state
- Assuming Wisconsin has constitutional carry — it does not. Concealed carry requires a Wisconsin CCW license (open carry of long guns/handguns is generally legal without a permit)
- Skipping the serial number on the bill of sale — without it, the document doesn't prove which specific firearm changed hands
- Confusing Wisconsin's eliminated 48-hour handgun wait (gone since 2015) with the federal NICS delay that can still happen at an FFL
Pro Tip
Wisconsin firearm law is permissive but not lawless: no permit, no wait, no registry — and no state background check on private transfers — but federal prohibited-person rules and CCW licensing for concealed carry still apply. A clean bill of sale with serial number is your only paper trail.
